Chapter 13.3, Problem 5PE

Interpretation Introduction

Interpretation: The reaction of decomposition of ${\text{H}}_{\text{2}}{\text{O}}_{\text{2}}$ is given. Whether the decomposition of ${\text{H}}_{\text{2}}{\text{O}}_{\text{2}}$ is the first order in ${\text{H}}_{\text{2}}{\text{O}}_{\text{2}}$ is to be identified. The rate constant at the given temperature is to be calculated.

Concept introduction: The rate of a chemical reaction is defined as a change in the concentration of reactants as well as products with respect to time.

The rate constant for a reaction is calculated by the formula,

$\ln \left[\text{X}\right]=-kT+\ln {\left[\text{X}\right]}_{\text{ο}}$

To determine: If decomposition of ${\text{H}}_{\text{2}}{\text{O}}_{\text{2}}$ is the first order in ${\text{H}}_{\text{2}}{\text{O}}_{\text{2}}$ and the rate constant at the given temperature.
